...We also add a turbulence model for the stress tensor in NS3d, which we consider to present anisotropy with respect to the vertical and the longitudinal scale: therefore two different eddy viscosities (vertical and longitudinal) are introduced following [18]....

...Following Levermore and Sammartino in [18], we observe that this relationship cannot be assumed to be isotropic because the horizontal and the vertical length scales will be of different orders in a shallow water approximation....

...In [18] authors introduced a further eddy viscosity, say the bulk viscosity μe and they made the physical assumption that μe should be much smaller than μh; but they were dealing with the rigid lid approximation; in our case, without any rigid lid approximation, we take μh and μe of the same order of magnitude....
